BQTTLE-STOPPER.

Specification of Letters Patent.

Application filed August 10, 1911.

Patented June 11, 1912.

Serial No. 643,397.

To all whom it may concern:

Be it known that 1, ANDREW H. TYSON, a citizen of the United States, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Bottle-Stoppers, of which the following is a specification.

My invention relates to an improvement in bottle stoppers, and the object is to pro- 1 is a view of the stopper before it is ap plied to a bottle, Fig. 2 is a view similar to Fig. 1, but showing the stopper in operative position upon the neck of the bottle, and Fig. 3 is a detail sectional view.

The bottle A is provided around its neck with an enlargement 1, and a pump B or other tube is adapted to be inserted through the mouth of the bottle for the discharg of the liquid therefrom. A cap Qhaving a central orifice 3 therein, is adapted to fit loosely around the pump B above the bottle-mouth and between the cap and mouth a flexible gasket 4c is interposed, the central orifice 5 of which is preferably of slightly less diameter than the pump. A spring 6 is received around the pump, and has its lower end resting upon the cap 2, and the upper end thereof is bent outwardly and downwardly to form a goose-neck 7 which is bent inwardly to form a hook 8 at its extremity.

In the-use of the device, the pump B is inserted through the mouth of the bottle, and the cap 2 and gasket 4 rest upon the mouth. Pressure is brought to bear upon the u )per end of the spring 6, and the gooseneck is forced outwardly so that the hook 8 will pass over the enlargement 1 on the bottle. hen the spring has been sufi iciently depressed that the hook 8 has passed over the enlargement 1, the goose-neck is released and the hook presses against the lower shoulder of the enlargement 1. In this position, the spring 6 engages pump B, due to the throwing out of the goose-neck 7 thus tending to hold the pump rigidly in place, and at the same time forming an air and liquid-tight seal between the cap and bottle mouth, and the cap and pump by reason of the pressure brought to bear upon the flexible gasket a by th spring. It is evident that the hook 8 could be adapted to any form of bottle-neck by reason of the flexibility of the goose-neck 7, and that it would hold equally well.

It will thus be seen that I have provided a device of the character described which is practically self-adjusting, and when once fitted to the bottle forms a liquid and airtight seal, which is not, likely to become disengaged therefrom.

Having fully described my invent-ion, what I claim as new and desire to secure by Letters Patent, is

The combination with a bottle-neck, acap and gasket, of a tube passing through the central orifice in the cap and gasket, and a spring encircling the tube and bearing against the cap, said spring having an integral hook in position to engage the bottle neck when the spring is compressed to resiliently force the cap and gasket against the bottle neck.

In testimony whereof I affix my signature in the presence of two witnesses.
